Superintendent Mark Morgan of Liverpool policing area said: "The events of Tuesday were totally unacceptable and we have had a lot of support, both from the local community and the media. As a result of information received during the investigation, we have been able to carry out this operation.

"Our actions today show that we are making every effort to identify and arrest those we suspect were involved in this despicable act, and it was fortunate that none of our officers were more seriously injured.

"We will continue our increased visibility of patrols in the area, and we would encourage members of the community to provide any information through 101, or via the confidential Crimestoppers line on 0800 555 111."
